Jade tree, known botanically as Crassula argentea and also commonly as jade plant, is an evergreen shrub or small tree. It is often confused with being a succulent, but technically it isn't. It is a tender, subtropical perennial that is grown most commonly as a houseplant, but grows as an outdoor shrub in temperate and tropical climes. Jade requires ambient temperatures of 65 to 75 degrees Fahrenheit during the day and overnight temperatures between 50 and 55 degrees. Beyond its natural range, the jade plant can be grown in containers outdoors in late spring and summer and moved indoors when temperatures drop in the fall.
Site your jade tree where it will have benefit of a full sun exposure or a combination of direct sun and very bright indirect light.
Water the jade tree to keep the soil evenly moist at all times. The fleshy stem can easily rot when the soil is kept soaking wet, so deep, infrequent watering is the best method. Don't allow the soil to become dry beyond the very top crust. If the plant is root bound or the soil quality so depleted that it cannot remain moist without frequent watering, it is time to transplant to a larger pot with fresh soil.
Feed your jade tree with a complete, balanced liquid houseplant fertilizer with a guaranteed analysis of 10-10-10. Dilute with water according to the product label directions every three months.
Prune only to remove damaged or diseased stems or foliage as no regular pruning is recommended. Consider your pruning cuts carefully as the jade tree is relatively slow growing and any holes or asymmetry will only be restored slowly over time.
